Below in conjunction with accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.The assembly of the embodiment of the present invention describing and illustrate in usual accompanying drawing herein can be arranged with various different configuration and design.Therefore, below to the detailed description of the embodiments of the invention provided in the accompanying drawings and the claimed scope of the present invention of not intended to be limiting, but selected embodiment of the present invention is only represented.Based on embodiments of the invention, the every other embodiment that those skilled in the art obtain under the prerequisite not making creative work, all belongs to the scope of protection of the invention.
Embodiment one
Consult Fig. 1 and Fig. 2, embodiments provide a kind of Manpower generation device, the gear that Manpower generation device includes hand cranking handle 101, shell 102, generator 103 and is arranged in shell 102.Wherein, gear comprises the first gear 105 and the first double-layer gear 106, first gear 105 and the first double-layer gear 106 are all arranged in shell 102 by gear shaft, the diameter of the first gear 105 is greater than the diameter of the internal layer gear of the first double-layer gear 106, and the internal layer gear mesh of the first gear 105 and the first double-layer gear 106 is in transmission connection.
Hand cranking handle 101 is in " L " type, one end of hand cranking handle 101 is connected with the gear shaft of the first gear 105 inner sleeve, thus the other end of hand cranking handle 101 can be moved in a circle along the coupling part of hand cranking handle 101 and this gear shaft under external force, and then the first gear 105 is driven to rotate.
The rotor of generator 103 is arranged with the second gear, being in transmission connection with the outer gear mesh of the first double-layer gear 106 of the second gear, and the diameter of the second gear is less than the diameter of the outer gear of the first double-layer gear 106.
103, generator is fixed on shell 102, and meanwhile, generator 103 is provided with the wire 104 for external output current, so that the electric current produced charges to electronic equipments such as mobile phone to be charged, charger baby.
When rotating hand cranking handle 101, first gear 105 rotates thereupon and drives the internal layer gear shaft of the first double-layer gear 106 to rotate, and then drive whole first double-layer gear 106 to rotate, diameter due to the first gear 105 is greater than the diameter of the internal layer gear of the first double-layer gear 106, and the speed that therefore the first double-layer gear 106 rotates is greater than the speed that the first gear 105 rotates.When first double-layer gear 106 rotates, its outer gear rotates thereupon and drives the second pinion rotation, the diameter of the outer gear of the first double-layer gear 106 is greater than the diameter of the second gear, therefore the speed of the second pinion rotation is greater than the speed that the first double-layer gear 106 rotates, when namely rotating hand cranking handle 101, the speed that the speed of the second pinion rotation is rotated considerably beyond hand cranking handle 101, thus make the High Rotation Speed of the rotor of generator 103, stable electric current can be produced during generator 103 inner cutting magnetic induction coil, so that to mobile phone, the electronic equipments such as charger baby charge.
Hand cranking handle 101, in " L " type, therefore, can take larger space, is not easy to place, and Given this, the Manpower generation device that the present embodiment provides adopts folding setting.Concrete, hand cranking handle 101 comprises link and crank two parts, and link is connected with the gear shaft of the first gear 105 inner sleeve, and is connected with crank, and the rotation direction of link is vertical with the rotation direction of the first gear 105.Be rotationally connected and can have multiple implementation, such as, be connected through the hinge or pinned connection, in the present embodiment, link and crank are connected through the hinge.Adopt above-mentioned set-up mode, can fold hand cranking handle 101, facilitate the placement of Manpower generation device.
In addition, for making the generating efficiency of Manpower generation device higher further, in the present embodiment, also in shell 102, be provided with the second double-layer gear 107, wherein, the outer gear of the first double-layer gear 106 and the internal layer gear mesh of the second double-layer gear 107 are in transmission connection, and the diameter of the outer gear of the first double-layer gear 106 is greater than the diameter of the internal layer gear of the second double-layer gear 107.Meanwhile, outer gear and second gear mesh of the second double-layer gear 107 are in transmission connection, and the diameter of the outer gear of the second double-layer gear 107 is greater than the diameter of the second gear.By arranging the second double-layer gear 107, when rotating hand cranking handle 101, the second pinion rotation speed is faster, and the generating efficiency of Manpower generation device is higher, thus promotes the charge efficiency entered the electronic equipment such as mobile phone, charger baby further, and more laborsaving during generating.
Certainly, the Manpower generation device that the present embodiment provides is not limited only in shell 102, arrange the first double-layer gear 106 and the second double-layer gear 107 two double-layer gears, the quantity of double-layer gear does not limit, such as adopt three double-layer gears or four double-layer gears, the quantity of double-layer gear specifically can be selected according to actual conditions, during multiple double-layer gear, mounting means consults the mounting means of the first double-layer gear 106 and the second double-layer gear 107, no longer describes in detail at this.
The Manpower generation device that the present embodiment provides, small volume and less weight, carry and use very convenient, particularly can realize charging to the electronic equipment such as mobile phone, charger baby whenever and wherever possible in the place (as train, automobile or field etc.) of some non-transformer access points.
